The social media giant Facebook has suspended Boston-based data startup firm from its site and says it is investigating whether the company’s contracts with the US government and Russian non-profit violated policies and also over concerns about how the firm used Facebook data.

Boston-based company has summed over more than a trillion public social media posts and also has agreements with different government agencies as the Wall Street Journal reported. It was co-founded in 2007 by a Harvard professor who currently leads Facebook’s independent research initiative focused on stopping election intrusion.

The firm, Crimson Hexagon, says major US corporations are allowed to become clients and examine audiences and to track brand awareness and campaign performance.

He claims that the company only gathers openly available social media data, an act which is completely legal. Whereas, Facebook and other social media firms are constantly working because of the pressure to improve and protect from being used to increase misinformation or false news, as US says Russia did during the 2016 US presidential campaign.

Boasting is said to be the world’s largest sets of unstructured social media datafirm, Crimson Hexagon has worked for the Department of Homeland Security, the State Department. In one case, the company unintentionally accessed confidential Instagram data.

Ime Archibong, Facebook’s vice president of product partnerships, said in a statement, “We are investigating the claims about Crimson Hexagon to see if they violated any of our policies.”

The investigation so far says that Facebook said the firm didn’t wrongly got hold of any Facebook or Instagram user data. The Journal said the government deals of Crimson Hexagon, which collect users data from Facebook, were not permitted previously by Facebook.
